Cambrian Coast Line: The coast line runs up the northern coast of Cardian Bay, from Machynlleth to Tywyn, Fairbourne, Barmouth, Harlech, Porthmadadog, Criccieth and Pwllheli.

NB: In general, if you're traveling from Shrewsbury on the Cambrian Lines, board one of the front 2 coaches to travel to Aberystwyth on the Main Line, and one of the 2 rearmost coaches to travel on the Coast Line. The train 'splits' at Machynlleth. Be sure to check with the guards in case of any change to this.
